Hi Edward,
Yes, In the design documentation[1] I wrote a sample of creating a data
object which is only replicated in one data center by adding meta-data to
the key.
For case 1 we can use empty values to dataCenter and replicateNodes
{
key: lock/foo,
replicateNodes: <List of all nodes in ds1>,
dataCenter: ds1,
expireOn: 2 min
}
For case 3 we can use a * (star) like special character for the
replicateNodes to indicate that value needs to be replicate in this data
center.
{
key: lock/foo,
replicateNodes: *,
dataCenter: ds1,
expireOn: 2 min
}
I didn't get the case 2, Can you please give an example for case 2 ?
